Method and apparatus for remote data access in a mobile communication device

Abstract

A method and apparatus for remote data access in a mobile communication device. A voice call can be initiated between a first voice and data wireless device and a second voice and data wireless device. A data access request can be communicated between the first voice and data wireless device and the second voice and data wireless device. The voice call can be switched to a data call to establish a data access connection. Data can then be transferred between the first voice and data wireless device and the second voice and data wireless device.

1. A method at a network controller on a wireless network of remote data access between a first voice and data wireless device and a second voice and data wireless device remote from the first voice and data wireless device, the method comprising:
 receiving a call initiation request from the first voice and data wireless device; 
 responsive to the call initiation request, initiating a voice call between the first voice and data wireless device and the second voice and data wireless device; 
 determining whether the voice call has been answered by the second voice and data wireless device; 
 if the voice call has not been answered by the second voice and data wireless device, receiving a data access request from the first voice and data wireless device, the data access request being separate from the call initiation request and indicating a request to access data from the second voice and data wireless device; 
 acknowledging the data access request; and 
 in response to the data access request, switching the voice call to a data call to establish a data access connection between the first voice and data wireless device and the second voice and data wireless device to thereby allow the first voice and data wireless device to retrieve data from the second voice and data wireless device, 
 wherein the first voice and data wireless device and the second voice and data wireless device are portable. 
 
     
     
       2. The method at a network controller of remote data access according to  claim 1 , further comprising determining if the second voice and data wireless device is camped on the network. 
     
     
       3. The method at a network controller of remote data access according to  claim 1 , further comprising determining whether the second voice and data wireless device is subscribed for a data access request service. 
     
     
       4. The method at a network controller of remote data access according to  claim 1 , further comprising:
 if the voice call has not been answered by the second voice and data wireless device,
 sending a data access request option to the first voice and data wireless device prior to receiving the data access request from the first voice and data wireless device; and 
 receiving the data access request from the first voice and data wireless device responsive to the data access request option. 
 
 
     
     
       5. The method at a network controller of remote data access according to  claim 4 , wherein sending a data access request option to the first voice and data wireless device further comprises sending a feature option to the first voice and data wireless device, the feature option including the data access request option and a voice mail request option. 
     
     
       6. The method at a network controller of remote data access according to  claim 1 , further comprising:
 sending a security prompt to the first voice and data wireless device; and 
 receiving a passcode from the first voice and data wireless device. 
 
     
     
       7. The method at a network controller of remote data access according to  claim 1 , further comprising determining an end of the data access connection by receiving an acknowledge data complete signal. 
     
     
       8. The method at a network controller of remote data access according to  claim 1 , wherein the network controller comprises a base transceiver station on a cellular network. 
     
     
       9. A system for remote data access between a first voice and data wireless device and a second voice and data wireless device over a wireless network, wherein the first voice and data wireless device and the second voice and data wireless device are portable, the system comprising:
 a network controller coupled to the wireless network, the network controller configured to control operations on the wireless network; and 
 a remote data access module coupled to the network controller, the remote data access module configured to:
 receive a call initiation request from the first voice and data wireless device at the network controller, 
 responsive to the call initiation request, initiate a voice call between the first voice and data wireless device and the second voice and data wireless device, 
 determine whether the voice call has been answered by the second voice and data wireless device; 
 if the voice call has not been answered by the second voice and data wireless device, receive a data access request from the first voice and data wireless device, the data access request being separate from the call initiation request and indicating a request to access data from the second voice and data wireless device, 
 acknowledge the data access request, and 
 
 in response to the data access request, switch the voice call to a data call to establish a data access connection between the first voice and data wireless device and the second voice and data wireless device to thereby allow the first voice and data wireless device to retrieve data from the second voice and data wireless device. 
 
     
     
       10. The system for remote data access according to  claim 9 , wherein the remote data access module is further configured to determine whether the second voice and data wireless device is subscribed for a data access request service. 
     
     
       11. The system for remote data access according to  claim 9  wherein the remote data access module is further configured to:
 send at least a data access request option to the first voice and data wireless device prior to receiving the data access request from the first voice and data wireless device if the voice call has not been answered by the second voice and data wireless device, and 
 receive the data access request from the first voice and data wireless device responsive to the data access request option. 
 
     
     
       12. The system for remote data access according to  claim 9 , wherein the remote data access module is further configured to send a security prompt to the first voice and data wireless device and receive a passcode from the first voice and data wireless device.
